The cameras would first undergo testing at the Hartsfield-Jackson Atlanta International Airport. CBP would then assess the data collected to determine if it aids CBP’s exit protocol for travelers.

If CBP can create a robust biometric tracking system–a way to identify individuals based on their unique physical characteristics like fingerprints, facial recognition, iris scan–it will enable the agency to better determine which individuals are "lawfully present in the United States from those who have violated their terms of admission."

This system would require agents to gather entry and exit data on travelers, and match their corresponding biometric attributes. This system would also make it more difficult for travelers to leave the country under another person’s name.

If the cameras are successful at airports, CBP intends to expand the program to cover land and sea ports.
